Gas Detection and Monitoring Solutions for Life Vol 8 NO 1 The Gas Detection People

Welcome to Industrial Scientific Since being founded in 1985, Industrial Scientific has sought to make a contribution to this world by helping people return home from work at the end of the day alive. We recognize that, at any given time, hundreds of thousands of people are betting their lives on the collective work we do as a company. That being said, it is important to know what drives your supplier of gas detection equipment and solutions. Here at Industrial Scientific, we are driven by three things. The first is Our Mission Preserving human life on, above, and below the Earth. Delivering highest quality, best customer service every transaction, every time. What we do preserving human life shapes our expectations towards the output. It must be of highest quality and exceed the expectations of our customers. We invest aggressively in capital equipment and business systems to ensure this. We partner with the best suppliers we can find. We don t let anything out of our factories that we wouldn t bet our own lives on. The second is our Employees First business philosophy. We believe good performance is the result of doing the right things for employees first, customers second and shareholders third. Only when we have the best people in the world, working with the best tools, can we truly deliver the best performance for our customers. If we serve our customers well, we will thrive as a company. It all starts, though, with the individuals designing, building and selling the solutions you and your people bet your lives on. We will not compromise by serving you with anything but the best people. Lastly, we are driven by our independence. Industrial Scientific was a publiclytraded company from 1993 to 1999. As a public company, we felt our mission and business philosophy were in opposition to the demands of Wall Street and outside shareholders. As a private company, we have been able to reinvest in our people and our systems, and make decisions with a better long-term focus. We actively work to keep Industrial Scientific strong and independent. If you are a current customer, thank you for your business and partnership. If not, I hope to have the opportunity to demonstrate what the great people of Industrial Scientific are capable of doing to help you create a safer workplace. If I can ever be of any assistance, please do not hesitate to contact me directly at +1-412-490-1842 or at jmcelhattan@indsci.com. Thank you. Justin McElhattan President and Chief Executive Officer

2 Three Keys to an Effective Gas Detection Program Industrial Scientific knows it s simply not enough to arm every worker in hazardous environments with a gas detector. Even the most reliable monitor cannot keep workers truly safe in the field if it is improperly used or poorly maintained. Successful gas detection programs include the following: Reliable Equipment Safe Behavior Every worker needs robust, reliable gas detectors and docking stations to keep them safe in hazardous environments. Gas detectors are completely ineffective if used improperly. Visibility into alarm events and unsafe behaviors provides teams the data needed to take the corrective and preventive actions that keep them safe. Painless Service Gas detection isn t core to most businesses, yet it requires significant time and money as instruments require regular maintenance and repairs. Cost-effective, timely and painless service is required to keep instruments in working condition and ready to protect. * Onsite installation and onsite training are optional for 1-5 docking stations and are included in installations with more than 5 docking stations. ** Calibration gas supply is not included in the pricing of any of our solutions.

8 Accenture Life Safety Solution Helping Achieve High Performance Safety using Intelligent Industrial Mobility Drawing on the combined capabilities and experience of Accenture, AeroScout, Cisco and Industrial Scientific, the Accenture Life Safety Solution is a comprehensive approach of services, technologies and processes (see Figure 1) which is differentiated from other safety solutions on the market by its breadth and innovative capabilities. Figure 1. Accenture Life Safety Solution built by strong capabilities and years of experience. Accenture AeroScout Cisco Industrial Scientific Industry-specific experience Integrated business processes Project management Unprecedented, design process Exciter hardware Integrated Wi-Fi tags Operator interface Wireless infrastructure inet - Gas Detection as a Service Multi-gas detector Accenture Life Safety Solution works Employees wear a single, multi-gas detector (within 10 inches of their breathing zone) that is able to detect multiple gases (see Figure 2). If abnormal levels of gas are detected, similar to traditional solutions, the device immediately alerts the employee. However, with the innovative Accenture Life Safety Solution, the device also simultaneously transmits the gas-level information and personnel location over a wireless infrastructure using an integrated Wi-Fi tag located in the Industrial Scientific device to control board operators. Until recently, wireless networks have been unable to provide reliable coverage, limiting the ability to determine an individual s exact location in the plant. Accenture has been able to demonstrate that this is now possible based on an actual refinerywide deployment. The gas detection information is sent to a control room that continuously monitors abnormal condition alarms 24 hours a day, 7 days a week. Additionally, the software indicates a separate alert if the individual either activates the panic button or exhibits lack of motion ( man down ). In the case of lack of motion, a local alert occurs first. The individual has the opportunity to acknowledge the alert and, if left unanswered, the alert is sent to the central control board operator. Once alarms are wirelessly transmitted, the control room operator can pinpoint the location of the employee in danger within very close proximity of their exact location. If rescue is required, the control board operator is able to advise the rescue team, not only of the location of the individual, but also of the environmental conditions in that area before they enter. Workers outside plant boundaries can also be covered with the wireless solution. Many plants have operators that need to go outside the plant to operate other remote facilities such as water intake facilities and tank farms. The Accenture Life Safety Solution is able to provide these personnel with the same coverage as if they were in the plant through a combination of Wi-Fi, global positioning systems and cellular communications within vehicles. One of the most important features of the Accenture Life Safety Solution is assurance that all alarms get reported. When an alarm is sent to the control board, workflow is triggered through the automatic creation of an incident in the incident tracking system. Figure 2.

9 Potential benefits of a comprehensive approach to safety The Accenture Life Safety Solution can help safety and operations managers in industries such as oil and gas, chemicals, petrochemicals, metals, utilities, mining and others deliver more comprehensive and effective safety programs, including: Improved 24x7 safety monitoring and timely responses For the individual: A gas detector alarms with abnormal exposure. A lack-of-motion sensor triggers when left unacknowledged. There is a panic button on the device. The alarm goes to the control board operator or others, as required. For the broader plant workforce: Gas-level monitoring is continuous and automatic, and thus notifies the rescue team of the environmental conditions before they enter the area. The automatic reporting helps to prevent placing other plant personnel at risk if an individual fails to report alerts. Greater and more accurate safety incident reporting Improved compliance through personnel location monitoring Optimized and more effective mustering procedures Ability to drive safety operational process improvement Wireless solution for higher plant performance Accenture uses a well-refined wireless network design approach for accurate location detection. With a location-based design, numerous workforce efficiency opportunities are possible to extend the return on the initial investment. Potential opportunities include: Improved contractor management and better maintenance planning Workforce enablement of handhelds, tablets and ruggedized notebooks Enablement of other technical benefits: Expansion of radio systems by usingvoice over internet protocols (VoIP) technology. Improvement of operator rounds and the transmission of local field information in real time. Installation of wireless video cameras for fence line surveillance. Establishment of lower-cost video collaboration methods through the reduced installation costs of underground hard wires for video cameras. Installation of motion sensors on the fence line to enhance security measures. Deployment of mobile video in the field to transmit continuous video feed to the control room and emergency control centers (ECC).

Operating temperatures above 50 C (122 F) may cause reduced instrument accuracy. Operating temperatures below -20 C (-4 F) may cause reduced instrument accuracy and affect display and alarm performance. AlarmAmp For higher-noise environments, the Tango s alarm volume, typically 100dB at 10 cm, can be increased nearly 10dB with the addition of the optional patent pending AlarmAmp. The Tango s alarm is louder than that of any other single gas instrument on the market.

21 DualSense Technology The Tango incorporates revolutionary patent pending DualSense Technology which includes two of the same type sensor for the detection of a single gas. The two sensor readings are processed through a proprietary algorithm and displayed as a single reading to the user. DualSense Technology was developed to address the major challenge of making sure workers are always using fully functioning, reliable instruments in the field. Until Tango, that required a bump test of the instrument before each day s use. DualSense Technology ensures that regardless of your current bump test policy, you will be significantly safer with the Tango than with any other single gas instrument on the market today*. New Bump Test Recommendation Instruments without DualSense Technology: Based on the data in the chart, Industrial Scientific recommends that a bump (functional) test be performed prior to each day s use for all instruments without DualSense Technology. If conditions do not permit daily testing, bump tests may be done less frequently based on instrument use, exposure to gas, and environmental conditions. The frequency of testing of instruments without DualSense Technology is best determined by company policy or local regulatory agencies. Instruments with DualSense Technology: Regardless of bump test frequency (from daily to monthly), Industrial Scientific s instruments with DualSense Technology are safer than traditional instruments without the technology. The frequency of bump testing for instruments with DualSense Technology is best determined by company policy or local agencies based upon regulatory, environmental and other company-specific factors. These conclusions and recommendations are based on field data, safe work procedures, industry best practices and regulatory standards to ensure worker safety. *Based on inet data DualSense Technology Increases Gas Detector Reliability Average number of failures per instruments 1 in every 570 instruments will fail 1 in every 48,590 instruments will fail Instruments without DualSense Technology Instruments with DualSense Technology Days between bump tests

Intrinsic safety is a design technique applied to electrical equipment and wiring for hazardous locations. The technique is based on limiting energy, electrical and thermal, to a level below that required to ignite a specific hazardous atmospheric mixture. How is intrinsic safety defined? Intrinsically safe equipment and wiring shall not be capable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a flam mable or combustible atmospheric mixture in its most easily ignitable concentration. Who verifies intrinsic safety? Equipment is tested and certified for intrinsic safety by independent third party agencies, such as Underwriters Laboratories (UL), Canadian Standards Association (CSA), Factory Mutual Research Corporation (FM) and the Mine Safety and Health Administration (MSHA). Independent testing ensures that your gas monitoring equipment is not only designed to be intrinsically safe, but meets all required standards for intrinsic safety. The following gases are heavier than air: Argon Butane Carbon Dioxide Chlorine Ethane Hexane Hydrogen Chloride Hydrogen Sulfide Methyl Ethyl Ketone Methyl Mercaptan Nitrogen Dioxide Nitrous Oxide Oxygen Phosphine Sulfur Dioxide Propane FUEL FIRE TRIANGLE OXYGEN SOURCE OF IGNITION Ref: R. Stahl Intrinsic Safety Primer 1988 National Electrical Code Article 504-2 Definition of a Intrinsically Safe Circuit 1996 A circuit in which any spark or thermal effect is incapable of causing ignition of a flammable or combustible material in air under prescribed test conditions.

It also provides correlation factors that help the safety technician and instrument operator determine the actual percentage LEL when the sample gas differs from the gas that was used to calibrate the unit. For example, if the unit reads 10% LEL in a pentane atmosphere, and was calibrated to methane, the actual percentage LEL is determined as follows: 1. Locate the table cell where the sample gas (pentane) intersects with the calibration gas (methane). 2. Multiply the cell's value (2.02) by the unit's LEL reading (10%) to calculate the actual concentration of 20.2% LEL. * The combustible gas list is not a comprehensive list of all combustible gases that can be detected by the MX6.
